Naturally, rain and spring water is drained from its catchment areas to the sea through a tributaries and main river system. However, to store and bring the water to the right place and at the right time, water storages and man made channels should be added to the river system. Together, the natural and man-made channels, create a hydrosystem that is able to support the water that is needed by the region for its development. A number of hydrosystem scenarios can be created, where hydraulic modeling is required to evaluate and understand the system's behaviour. Furthermore hydraulic simulations can be performed to look for an optimum solution in term of the least cost for providing a cumec of water or to fulfil other criteria.

Climate change threatens food production, agriculture, water supply, as well as the existance of small islands, coral reefs, and wetlands. What are we going to do about it? Carbon trading is one way that has been seen as an important action, which every countries has to do in reducing the greenhouse gas pollution. Under the scheme that known as "cap and trade", each government sets an overall limit on the amount of carbon the economy can produce and provides permits to industry up to the nominated amount. A carbon intensive industry has to pay extra if they exceed their allocation. Asia’s mega delta cities are of the most expose to the impact of climate change’s through the floods. (Borneo-post, December 6, 2007) In the first volume of a triple report on global warming, published in February 2007, the UN Intergovernmental Panel on Climate Change (IPCC) said see levels would climb between 18 and 59 centimeters by 2100. According to OECD (December 2007), of 136 port ci

Interstate water transfer is like no body's concern in a country like Malaysia, where water resources management in under State Governments. This is a serius matter for States that has shortage of water resources, and Federal Government should be able to provide solution whenever needed. In the case where two or more states sharing water from the same river, the role of Federal Government or National Water Council as coordinating body is obvious. One example in Malaysia is Kedah and Penang States that sharing Sungai Muda. Most of the water is generated from Kedah, and the downstream stretch of the river appears as the border between Kedah and Penang (Seberang Prai). Four Dams are storing the river water in Kedah (Pedu, Ahning, Muda, and Beris). What is the sharing formula for water utilization that can be accepted by both States?

ABSTRACT Water resources development should be managed effectively for a sustainable regional development. Changing in management from fragmented to an integrated approach is recommended as a necessary undertaking. Changes will likely be wide-ranging, include institutions and policies at national, states, and river basin level, technology and infrastructure, and financial mechanisms. The areas requiring change, amongst others include: The role of the state in water resources development, management and use; Systems to reconciling water quantity and quality needs of all water users; and institutional reform and development to improve the effectiveness of management agencies. These changes in management required a capacity development at national level down to the river basin level. River basin has to be treated as a unit that should be consider for every development and management activities. Certain principles should be adopted, and the right instruments should be carefully selected in

Kuching city of the Sarawak State, Malaysia is located on a flat alluvial plain 30 km away from the sea. The city is divided to north and south parts by the tidal Sungai Sarawak. The low-lying city is vulnerable to high tides, where the city had experienced recorded spring tides as high as 6 m. The worst scenario of flooding happens when high runoff from the upstream catchments coincided with high tides from the downstream. In 1998, a barrage is established near estuary to protect the city. The structure is the property of the State Government under the care of Sarawak Rivers Board, but the operation is managed by a private contractor. The Sungai Sarawak Barrage has been in operation for 10 years and it is increasingly playing critical roles as a center of flood management for the region. The operation team extensively regulates and maintains the quality hydrological data of the river system with its telementry system. Recently, it functions also as a flood warning center entrusted by
